1.What is Submersible Dredge Pump

The submersible dredge pump is an excellent water conservancy machinery dedicated to efficient operation. The submersible dredge pump ensures seamless operation by using a unique structure in which the motor and pump are coaxially immersed in the medium. Its rigorous material selection, advanced structure, wide flow channel, and strong sewage discharge capacity make it significantly different from traditional pumps. Submersible dredge pumps are specifically designed to transport liquids containing solid particles such as sand, cinders and tailings. In industries such as metallurgy, mining, and thermal power plants, it plays a key role in the removal and transportation of mud liquids. The submersible dredge pump designed by OCEAN Pump draws on advanced foreign technology. In addition to the main impeller, a set of stirring impellers are added at the bottom of the pump, which can spray the deposited slag into turbulent flow, allowing the pump to achieve high-concentration transportation without the need for auxiliary devices. Its unique sealing device operates stably and greatly extends its service life. The motor is equipped with overheating protection, and various protection devices such as water inlet detection can be added according to user needs to ensure long-term safe operation under harsh working conditions.

2. Design features of submersible dredge pumps

2.1 Compact structure and small footprint

The submersible slurry pump produced by OCEAN Pump adopts an integrated design. The special motor is coaxially connected to the pump body, and the power is transmitted to the impeller through the motor rotor, forming a compact single structure. Compared with vertical slurry pumps, this design makes the pump body more compact and reduces the volume. The tightly coupled pump body and motor reduce noise and vibration, helping to reduce energy loss and resistance. Reducing transmission losses increases flow and head while maintaining the same power.

This design feature brings multiple benefits. First, the small size contributes to the portability and installation flexibility of the submersible slurry pump, making it suitable for environments with limited space. Secondly, reduced noise and vibration reduce environmental disturbances and improve workplace comfort. In addition, by reducing energy losses, submersible slurry pumps are more efficient during long-term operation, reducing energy consumption.

In practical applications, the unitary structure and compact design of this submersible slurry pump make it easier to maintain and manage. Maintenance personnel can perform inspection and maintenance more conveniently, reducing maintenance costs. At the same time, the tightly coupled design reduces friction and wear during operation, extending the service life of the pump.

2.2 Simple installation and maintenance process

Submersible dredge pumps are designed to be easily submersible underwater or in mud, without the need for cumbersome external installation processes. This type of pump comes with a range of mounting options to suit a variety of application scenarios while ensuring stability in its positioning and safe placement. The pump body is equipped with a discharge hose or pipe to efficiently transport dredged material to the designated location. OCEAN Pump is committed to providing customers with one-stop solutions, including but not limited to hulls, winches, operating systems, pump systems, rubber pipes, PE pipes, etc. The whole set of equipment is easy to install and maintain. Before leaving the factory, OCEAN Pump will customize the hull size for customers based on a reasonable design to ensure the buoyancy of the hull, film installation instruction videos for customers, and remotely guide customers in equipment installation and testing. This move is intended to reduce installation and maintenance costs. In addition, in order to ensure the long-term stable operation of the equipment, OCEAN Pump has also made great efforts in material selection and process processing. The materials they select undergo strict quality testing to ensure they are corrosion-resistant, wear-resistant, and able to adapt to various harsh environmental conditions. In terms of process processing, OCEAN Pump adopts advanced production technology to ensure the precision manufacturing and long-term stability of the equipment.
At the same time, OCEAN Pump also provides customers with a full range of technical support and services. Whether it is installation guidance, operation training, or equipment troubleshooting and maintenance, they can respond quickly and provide customers with timely and effective solutions. This worry-free service model greatly reduces customers’ operating costs and time costs, allowing them to focus on their core business.

2.3 Long continuous running time.

The sturdy construction of the submersible dredge pump ensures its durability in harsh working conditions. Usually, OCEAN Pump submersible dredge pumps are made of high-quality materials such as high-chromium alloy to meet the strict needs of dredging operations. This rugged construction allows the pump to continue operating without compromising performance.
Additionally, the pump’s efficient hydraulic design optimizes energy transfer and minimizes internal losses, thereby increasing overall efficiency. This reduces the pressure on the motor, allowing the submersible dredger pump to operate continuously for long periods of time.
On this basis, OCEAN Pump equipped the submersible dredge pump with a frequency conversion control cabinet, which to a certain extent protects the motor from overcurrent during instantaneous startup and ensures the safety of the motor startup. At the same time, the control cabinet is also equipped with motor overheating protection, water ingress protection and oil chamber protection measures to ensure that the pump works safely and reliably during long-term operation.

2.4 No cavitation

The design and implementation of the submersible dredge pump is the result of in-depth research and innovative practice by engineering and technical personnel to address problems such as cavitation damage and water diversion that occur during the use of traditional pumps. The core concept is to ensure that liquids flow smoothly and unobstructed, thus bringing great convenience to operators while minimizing potential operational risks.
First of all, in terms of pump design, OCEAN Pump researchers optimized the pump structure to improve the pump’s anti-cavitation performance. By optimizing the design of the inlet and outlet of the pump, the inlet pressure is reduced and cavitation is avoided. At the same time, special materials and coating technology are used to improve the wear resistance and corrosion resistance of the pump and extend the service life of the pump.
Secondly, in terms of pump operation control, OCEAN Pump adopts an advanced control system to realize automatic adjustment and protection of the pump. When an abnormality occurs during pump operation, the control system can immediately initiate protective measures to avoid equipment damage. In addition, the friendly operation interface allows the operator to easily grasp the operating status of the pump, reducing operating difficulty and risks.
